Yea, the guy that tinted my truck warned me that polarized glasses will look funky through the tinted windshield. But he also pointed out, that with my setup, you shouldn't need sunglasses while in the truck.
I’ve got a 70% tint (Llumar Formula One Stratus) on my windshield, and I do notice a few rainbows when wearing polarized sunglasses, but it doesn’t bother me.
I also only see them in the sky—above the horizon, above trees, etc. I don’t see them on the road or when looking at other cars. It’s noticeable (in the sky), but not bothersome. If it did bother me, I’d get a pair of cheap, non-polarized glasses for driving and leave them in the truck (or try to; I usually forget and take them with me then curse myself when they’re not there on the next trip).
My tint guy also said I wouldn’t need sunglasses, but I still use them. Perhaps with a darker tint or a visor strip, sunglasses wouldn’t be necessary, but I wonder if “you won’t need sunglasses!” Is marketing fluff.
Fluff or not, I’m so glad I did ceramic tint, and especially glad I did the windshield. We took a 2,000 mile road trip, and wow, what a difference this makes when the sun is beating down on you.
For those in the Atlanta area, I went to The Tint Guy in Kennesaw, and they did a great job. My truck is with them for a few days for PPF right now (I miss her!).
